The invention concerns a method for activating a function by using a measurement taken from at least one digital image () having at least two colors () and originating from an image-capturing apparatus, the method including measuring the relative sharpness () between at least two colors in at least one region R of the image, and Controlling at least one action () depending on the measured relative sharpness.

Method for activating a function, namely an alteration of sharpness, using a colour digital image

A method for activating a function by using a measurement taken from at least one digital image having at least two colors and originating from an image-capturing apparatus, wherein a relative sharpness is measured between at least two colors on at least one region of the digital image, and at least one function is activated depending on the measured relative sharpness.

Method of controlling an action, such as a sharpness modification, using a colour digital image

A method and system for detecting an object in a zone located proximate to an interface between two liquid and/or gaseous media having different refractive indices, for example of the air/water type. The method and system produce at least a video image of the interface and the zone and produces electric signals representing each video image. Then, the electric signals are digitized and the data is processed by discriminating the data corresponding to the video image of the real object from those corresponding to the apparent video image generated by the interface.

Method, system and device for detecting an object proximate to a water/air type interface

A method for detecting new objects in a scene illuminated by lights not necessarily constrained. The method detects and produces, in particular with a video camera, in the form of electric signals, video images, at successive times, digitizes the resulting electric signals, and produces image digital data, in particular pixels, at successive times. Then, the image digitalis stored and the type of object, the trajectory, and attitude changes of the object are estimated.

Method for detecting new objects in an illuminated scene

The invention relates to a method for detecting an object () in relation to a surface (). A synthetic image () is produced from at least two distinct viewpoints (), for each of said viewpoints, by means of a geometrical transformation comprising at least one perspective projection () of the object on the surface (), each synthetic image being associated with the viewpoint concerned. By discriminating between the synthetic images, it is possible to detect the presence of and determine the position of the object () in relation to the surface (), by searching for contrast inversions. The invention can be used for surveying a swimming pool.
